✨ NAME ✨

Bestie, welcome to the fifo_icap_fifo_read(9) page from the Kernel API Manual — she's here to read data from the Read FIFO, and honestly? iconic behavior 💅

fifo_icap_fifo_read — reads data from the Read FIFO. That's the gig. Slay.

🌸 SYNOPSIS 🌸

u32 fifo_icap_fifo_read (struct hwicap_drvdata *drvdata );

---

🎀 ARGUMENTS 🎀

• drvdata — a pointer to the drvdata. Yes bestie, that's the whole description, and we respect the minimalism 🫶

---

🦋 DESCRIPTION 🦋

Heads up, bestie: this function will silently fail if the fifo is empty 😭

That's the warning. Silent. No cap. Don't expect a whole dramatic speech from her about it.

---
